JavaScript set entries() Method

  • by

JavaScript set entries() Method used to return a new Iterator object that contains an array of key-value pairs for each element in the Set object, in insertion order.

set.entries()

Note: The set does not contain key-value pairs, to keep similarities with the map entries() method, it will return key-value pairs with the same value.
